Abstract
The invention discloses a process for coating liquid medicine on surfaces of patterns and letters on a sheet material to form a protecting film. The process comprises the following steps: a coating rubber roll is driven to rotate through a motor; a material guide roll is driven to rotate in the same direction through another motor; a liquid medicine roll is arranged behind the coating rubber roll, and is clung to and extruded with the coating rubber roll; liquid medicine enters the space between the liquid medicine roll and the coating rubber roll through an injection port; the liquid medicine roll is driven to rotate through a motor, so as to generate a medicine film with certain thickness on the surface of the coating rubber roll; simultaneously, the material to-be-coated is guided by the guide roll, and passes through the gap between the guide roll and the coating rubber roll; and the medicine film is coated on the material to-be-coated. According to the process, the film coated on the sheet material is level, the quantity of micro-pores is greatly reduced, and requirements for solidification can be met without further carrying out a flattening step.
Description
Technical field
The invention belongs to a kind of coating process that is covered with one deck diaphragm in sheet surface, specifically a kind of surface of sheet material pattern, literal that liquid is coated on is to form the protection diaphragm or liquid is coated on sheet surface to form the technique for coherent films such as transfer printings.
Background technology
Traditional method that is covered with diaphragm at sheet material, system utilizes motor-driven material guide roller, drive coating rubber roll and do the rightabout rotation, and in coating rubber roll the place ahead the liquid roller is set, liquid roller and coating rubber roll are close to extruding mutually, liquid is entered between liquid roller and the coating rubber roll by inlet, be driven in the rotation of coating rubber roll by the liquid roller, and produce certain thickness medicine film on the surface of coating rubber roll, simultaneously, lining material through the space between material guide roller and the coating rubber roll, and is coated on the lining material medicine film by material guide roller guiding.
The laminated sheet that obtains of method thus, diaphragm thickness determine by material guide roller and coating rubber roll gap size, sheet thickness, and usually, diaphragm thickness system is realized regulating by the size of material guide roller and coating rubber roll gap.Because the frame for movement self reason, there is larger error in the adjusting of this gap length, and especially for thin overlay film, then seeming is difficult to control.
Even more serious, overlay film by the traditional handicraft generation, also have micropore and concavo-convex on it, rear road program exist to be eliminated the step of the concavo-convex and micropore of diaphragm, and existing step has utilizes gravity to shakeout, have and adopt blast to shakeout, also have by infrared radiation and eliminate micropore, etc., the lining material that all requires is in steps divided on equipment, this not only must take than large space, and has prolonged formation time.
Summary of the invention
The object of the present invention is to provide a kind of on sheet material the technique of overlay film, it improves existing technique, can reduce largely micropore on the diaphragm, eliminate the concavo-convex phenomenon of membrane surface.
Technique of the present invention is realized by following scheme:
A kind of on sheet material the technique of overlay film, be characterized in: rotated by a motor-driven coating rubber roll, do equidirectional rotation by another driven by motor material guide roller, and the liquid roller is arranged on the coating rubber roll rear, liquid roller and coating rubber roll are close to extruding mutually, liquid is entered between liquid roller and the coating rubber roll by inlet, rotated by a motor-driven liquid roller again, and produce certain thickness medicine film on the surface of coating rubber roll, simultaneously, lining material is led by guide roller, and the space through between material guide roller and the coating rubber roll then is coated on the medicine film on the lining material.
Thus obtained laminated sheet, the overlay film on it is smooth, and micropore has also greatly reduced, and need not further adopt the measure of shakeouing then can satisfy curing, can greatly reduce the length of equipment, the efficient of raising equipment.
Technique of the present invention is no longer continued to use and is attempted to utilize lining material to be come the measure of floating medicine film by coating rubber roll through the gap between material guide roller and the coating rubber roll in the past after lining material is coated liquid, has but obtained good effect.
Invented technology is deposited in liquid on the lining material because application step mainly is to be arranged in lining material through after the space between material guide roller and the coating rubber roll, makes on the contrary membrane surface more smooth, and has obtained a kind of new coating process.
Technique of the present invention is compared with existing technique, because application step mainly is to be arranged in lining material through after the space between material guide roller and the coating rubber roll, thereby can overcome that application step is arranged in before the space of material guide roller and coating rubber roll and among and have subsequently that coating rubber roll produces the problem of peeling off with the medicine film that has been coated with, reduced owing to peeling off the micropore that forms on the overlay film surface on the contrary and concavo-convex.
In addition, in technique of the present invention, overlay film thickness no longer is subject to the impact of material guide roller and coating rubber roll gap size, and depends on the velocity ratio of material guide roller and coating rubber roll, and the rotation direction of liquid roller, speed, with the size in coating rubber roll gap.
In the above-mentioned technique, when the speed of material guide roller and coating rubber roll when increasing, obtain the overlay film thinner thickness; Otherwise, obtain overlay film thickness thicker.
In the above-mentioned technique, when the rotation direction of the rotation direction of liquid roller and coating rubber roll is consistent, obtain the overlay film thinner thickness; When the direction of rotation of the rotation direction of liquid roller and coating rubber roll, obtain overlay film thickness thicker.
In the above-mentioned technique, when the rotation direction of the rotation direction of liquid roller and coating rubber roll is consistent, if reduce the velocity ratio of liquid roller and coating rubber roll, then obtain overlay film thickness thinner.
In the above-mentioned technique, when the direction of rotation of the rotation direction of liquid roller and coating rubber roll, if increase the velocity ratio of liquid roller and coating rubber roll, acquisition overlay film thickness is thicker.
Like this, can utilize above-mentioned means to realize overlay film thickness is regulated.Because diaphragm thickness is thinner, regulated by mechanical clearance, realize that the accurate control of diaphragm thickness then seems difficult, and carry out meticulous adjusting by above-mentioned means, implement and just become simple.
Realization is carried out meticulous adjusting to overlay film thickness, can select according to the purposes of lining material, for example, when selecting diaphragm thickness thicker, can make the concave-convex sense on lining material surface further alleviate and improve flatness, and the third dimension of enhancing lining material pattern; When selecting diaphragm thickness thinner, can make thin lining material keep soft, reduce the pliability that affects lining material owing to overlay film, can reel to satisfy sheet material.
